Although those numbers may have changed slightly since 2000, there is still truth in the observation that:

For Women in corporations, it can be extremely lonely “at the top.”

As a corporate coach & consultant for over 35 years, I have worked with senior women at the VP and Director levels who are often the only woman on the senior staff. They report everything from having their ideas repeatedly “stolen” to feeling like an “outsider”. They each, at some point, began to question their contributions/value since they were not getting the attention they thought their ideas deserved. Women at the senior level are essential. They need support in bringing the perspective only they can bring to the executive table. Although they excel at leadership within their departments, it may be an entirely different story at executive staff meetings.
